Hello, I am new to compiling gcc and have been running into an error with 6.3.0. Here's the scenario: 1. I am performing this on a Vagrant Ubuntu 16.04 machine 2. I have walked through the compilation steps here (installed binutils 2.27, all pre-requisites) and am receiving the error when I attempt to do `make all-gcc` http://wiki.osdev.org/GCC_Cross-Compiler#The_Build 3. This progressed along, until finally returning the error below. Can anyone offer any guidance on the issue? Is this a bug in 6.3.0? **Configure script:** sudo ../gcc-6.3.0/configure --target=x86_64-darwin --prefix="/home/ubuntu/opt/cross" --disable-nls --enable-languages=c --without-headers --disable-multilib **Full Error** g++ -fno-PIE -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -Woverloaded-virtual -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -DHAVE_CONFIG_H -I. -I. -I../../gcc-6.3.0/gcc -I../../gcc-6.3.0/gcc/. -I../../gcc-6.3.0/gcc/../include -I../../gcc-6.3.0/gcc/../libcpp/include -I/home/ubuntu/src/build-gcc/./gmp -I/home/ubuntu/src/gcc-6.3.0/gmp -I/home/ubuntu/src/build-gcc/./mpfr -I/home/ubuntu/src/gcc-6.3.0/mpfr -I/home/ubuntu/src/gcc-6.3.0/mpc/src -I../../gcc-6.3.0/gcc/../libdecnumber -I../../gcc-6.3.0/gcc/../libdecnumber/dpd -I../libdecnumber -I../../gcc-6.3.0/gcc/../libbacktrace -I/home/ubuntu/src/build-gcc/./isl/include -I/home/ubuntu/src/gcc-6.3.0/isl/include -o darwin-driver.o -MT darwin-driver.o -MMD -MP -MF ./.deps/darwin-driver.TPo ../../gcc-6.3.0/gcc/config/darwin-driver.c ../../gcc-6.3.0/gcc/config/darwin-driver.c: In function ‘void darwin_driver_init(unsigned int*, cl_decoded_option**)’: ../../gcc-6.3.0/gcc/config/darwin-driver.c:302:34: error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive] char *first_period = strchr(vers_string, '.'); ^ ../../gcc-6.3.0/gcc/config/t-darwin:35: recipe for target 'darwin-driver.o' failed make[1]: *** [darwin-driver.o] Error 1 make[1]: Leaving directory '/home/ubuntu/src/build-gcc/gcc' Makefile:4124: recipe for target 'all-gcc' failed make: *** [all-gcc] Error 2
